WIRE-OPERATING DEVICE FOR PILE-FABRIC LOOMS.

SPECIFICATION forming part of Letters Patent No.426,284, dated April 22, 1890.

Application led September 9, 1889. Serial No. 323,453. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM KQTHE, a citizen of the United States, residing at Thompsonville, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Wire-Operatin g Devices for Pile-Fabric Looms, of which the following is a speciiication. y

This invention relates to looms for weaving pile fabrics, the object beingi to provide for looms of this class improved wire-motion or wire-operating devices, by Ineans of which the pile-wires are operated with greater rapidity than has heretofore been done, and whereby the wire-operating devices can be changed or adjusted for operating either the plain wires for weaving Brussels carpets or the cuttingwires for weaving lViltons with much greater facility than has heretofore been possible; and the invention consists in the construction and arrangement of the said wire-operating devices, all as hereinafter fully described, and pointed out in the claims.

In the drawings forming part of this speciication, Figure 1 is a side elevation of a portion of a loom for weaving pile fabrics having my improvements applied thereto. Fig. 2 is a perspective View of a detail part hereinafter fully described. Fig. 3 is a side elevation of detail parts of my said improvements hereinafter fully described. Fig. 4 isa perspective view of a detail part hereinafter fully described. Fig. 5 is a perspective view of a portion of a pile-fabric loom, showing a portion of a partially-woven fabric therein and operative portions of my improvements in connection therewith, all as hereinafter fully described.

In the drawings, A indicates portions of the frame of a pile-fabric loom, and 2 the main driving-shaft thereof, to which rotary motion is imparted by a belt, as shown, or other suitable means. The crank-shaft 5 of the loom, as well as said main shaft 2, run in suitable boxes in said frame, and said crank-shaft has the gear 4 xed thereon, which engages witha pinion 3, fixed on said driving-shaft, whereby the crank-shaft' is given the requisite rotary motion. The picker-shaft 9 is also supported in suitable boxes on the frame of the loom, and is given a rotary motion. in the usual well-known way by suitable connection with said driving-shaft 2, said connection not being deemed necessary to be illustrated in the drawings.

The above-referred-to improved wire-Inotion or wire-operating devices of the loom are operated by connection with said pickershaft 9, as below described. A plate-gear (so termed by loom-constructers) 6 is placed on the said crank-shaft 5, and turns loosely thereon, said plate-gear being shown'separate from the loom in Figs. 2 and 3, and it has a beveled pinion 8 fixed upon the hub thereof, as shown in said figures, and on the outer face of said plate-gear is bolted a segment 7 of a beveled gear, said segment embracing about one-half of a complete gear of that dimension, and the said plate-gear engages With a gear 10, xed on said pickershaft, whereby the plate-gear is given a rotary motion independent of the shaft 5, on which it rotates.

A wire-motion crank-shaft 12 is supported in suitable bearings in the frame A of the loom, having on one end the crank 21, and its opposite end, terminating opposite the face or outer side of said plate-gear 6, is adapted to have secured thereon either one of two pinions 13 or 14, one for engagement with the `pinion S on the hub of said plate-gear and the other one 14 for engagement with said geared segment 7, said pinion 13 being employed to impart a constant rotary motion to said crank-shaft 12when Brussels carpets are being woven on thev loom, and the pinion 14 for engagement with the geared segment 7 when Wilton carpets are being woven, thereby imparting an intermittent rotary motion to said crank-shaft 12, thereby leav`v ing said shaft and the wire-operating devices with which it is connected, as below described, at rest during one-half of the revolution of said plate gear, as is required in weaving Vilton carpets, said rest being provided for to permit the three lay movements in Wilton Weaving, Brussels requiring but two of such movements, and the lay devices would not have time to operate in Vilton weaving were it not for said rest of parts. derstood by the above description that the said pinions 13 and 14 are used exchangeably on thecrank-shaft 12,

and each of said IOO It will be unpinions is rigidly secured in its proper place on said shaft when employed, as aforesaid, by a set-screw through the hub thereof engaging with said shaft, or by other suitable well-known means whereby the pinion is held improper position on the shaftwhile being employed.

By reference to Figs. 3 andiit will be seen that the said beveled segment 7 has at each end of the group of gear-teeth thereon a proj ection or extension z at right angles to the adjoining side of the plate-gear 6, and that the pinion 14 has a long tooth 15, and when the said pinion is operating on the crankshaft 12 in conjunction with the geared segment 7, as above described, the said long tooth 15 is brought into engagement with one of said projections z on said segment each time that the latter comes around into engagement with said pinion,whereby the proper relative positions of said pinion and segment are definitely insured at the instant of their engagement, the first start of said pinion and its shaft being induced by the impact of one of said projections against said long tooth, and the teeth of the segment and of the pinion 14 immediately following in proper engagement,thereby preventing any hinderance to the proper engagement of said geared parts by a possible misplaced position of any of the teethof the pinion by an undue rotation of the crank-shaft by impetus or otherwise, whereby the teeth of the segment and of said pinion might be hindered from proper engagement with each other after the said rest in the rotary movement of said shaft.

It is intended that in practice each rotary movement of the crank-shaft 12 shall be that of a full revolution thereof, and as a means for insuring as far as possible the stopping of said shaft after said revolution, and yet to permit the latter to be again rotated by said driving mechanism, a stop-disk 1G is fixed on said crank-shaft, in the periphery of whichis a stop-notch Qc; and a lever 17 is pivoted by its upper end to the loom-frame, and is adapted to have a vibratory motion toward and from the outer side of the crank-shaft 12, a spring 18, connected to its lower end, drawing said lever toward said shaft, and in said lever opposite said shaft is fixed an arm 19,which extends opposite the periphery of said stop-disk 16,whose free end is made to rest against the edge of said disk, and by the action of saidl spring 1S upon the lever 17 is caused to drop into and engage with said stop-notch x at each revolution of said crank-shaft. A friction-roller e is placed on that part of said arm 19 which engages with the edge of said friction-disk. In changing the said wire-operating mechanisms, as aforesaid, from their arrangement as described for weaving Wilton Y carpets the said change is effected by simply replacing the pinion 14 with the pinion 13 on shaft 12 and by removing the lever 17 from the loom; and to rearrange the wire-motion devices for weaving Viltons the pinion 13 is replaced by the pinion 14: and the lever 17 is reattached to the loom. Thus it will be seen that either of the above-mentioned changes can be effected in a few moments, whereas by the devices heretofore employed such changes have required that the loom be stopped several hours therefor.

The needle-horse (so termed by loomconstructers) 25 has the usual reciprocating motion horizontally on the upper part of the loom-frame on a fixed part thereof B, Fig. 1, said motion being imparted thereto by the connection with a stud w on the side of said horse of the upper end of a lever 20, which is connected with said stud by a link 24,*said lever being pivoted on a suitable stud K on the loom-frame, and having its lower end connected by a connecting-rod 22 with the'crank 21 on the crank-shaft 12. The said needlehorse is connected in the usual way with the part of the needle devices 2G usually terlned the hoppen with which engages in the usual manner the usual handy or gage-arm" 30, (see Fig. 5,) to which is connected the usual gage 31. Said hopper has pivoted on the side of its lower end the usual ellipses y y, against the upper one of which is arranged a spring 27 and against the lower one a spring 28, whereby said ellipses shall be caused to more effectually engage the rear or butt end of the wire 29.
